Merge tag 'drm-msm-next-2023-06-18' of https://gitlab.freedesktop.org/drm/msm into drm-next
Updates for v6.5.. this includes a backmerg of drm-next tree to be able to use new DRM DSC helpers. Core: + Add Marijn Suijten as drm/msm reviewer + Adreno A660 bindings + SM8350 MDSS bindings fix + Fix adreno_is_a690() warnings + More generic (DRM) and MSM-specific DSC helpers DP: + Removed obsolete USB-PD remains + Documented DP compatible string for sm8550 platform DPU: + Enable missing features (DSPP, DSC, split display) on sc8180x, sc8280xp, sm8450 + Enabled writeback on sc7280 + Implemented tearcheck support to support vsync on SM150 and newer platforms + Native HDMI output support + Dropped unused features: regdma, GC, IGC + Fixed the DSC flush operations + Simplified QoS handling, removing obsolete and unused features and merging SSPP and WB code paths + Reworked dpu_encoder initialisation path + Enabled DSPP support on sdm845 + Disabled color-management if DSPP blocks are not available + Added support for DSC 1.2 blocks found on sm8350 and later + Added .fb_dirty to fix CMD panels DSI: + Drop powerup quirks in favour of using pre_enable_prev_first for downstream bridges + Fixed 14nm DSI PHY programming + Added support for DSI and 28nm DSI PHY on MSM8226 platform + Make use of DRM and MSM DSC helpers MDP5: + Added support for display controller on MSM8226 platform GPU: + A690 support + Don't set IO_PGTABLE_QUIRK_ARM_OUTER_WBWA on devices with coherent SMMU (like A690) + Move cmdstream dumping out of fence signaling path + Cleanups + Support for a6xx devices without GMU (aka "GMU wrapper" + a610 support + a619_holi support (a619 variant without GMU) Signed-off-by: Dave Airlie <airlied@redhat.com> From: Rob Clark <robdclark@gmail.com> Link: https://patchwork.freedesktop.org/patch/msgid/CAF6AEGsUB=tRB4nR6ZCJMuLhro5zN3BQWUSywVYbaipqqDZ_cQ@mail.gmail.com
